BEHAVIORAL MANAGEMENT OF EXERCISE TRAINING IN VASCULAR HEADACHE PATIENTS: AN INVESTIGATION OF EXERCISE ADHERENCE AND HEADACHE ACTIVITY

A behavioral package was used to shape and maintain the adherence of 5 subjects with vascular headache to a program of aerobic exercise training. Repeated measures of exercise behavior were examined through the use of a bidirectional changing criterion design. Repeated measures of headache activity were also collected. Results demonstrated a functional relationship between the behavioral package and exercise adherence, because all 5 subjects showed exercise behavior that matched bidirectional changing exercise criteria. The results also indicated clinically significant collateral reductions in vascular headache activity in 4 subjects. Subjects whose aerobic fitness levels were not masked by vasoactive medication also showed measurable increases in aerobic fitness. The results are discussed in terms of the methodology used to demonstrate a functional relationship between the adherence package and exercise behavior and the possible mechanism(s) by which aerobic exercise activity might affect vascular headache activity.     

Habituation at home

Habituation to mother's face in naturally occurring en face social interactions and to a single object in naturally occurring solitary play was studied in American and Japanese infants. Habituation was observed in both conditions in both samples, and home habituation data paralleled analogous laboratory habituation data both quantitatively and qualitatively.     

THE CHANGING CRITERION DESIGN

This article describes and illustrates with two case studies a relatively novel form of the multiple-baseline design called the changing criterion design. It also presents the design's formal requirements, and suggests target behaviors and circumstances for which the design might be useful.     

A review of observer reactivity in adult-child interactions

The present article reviews studies which have examined the question of observer reactivity in adult-child interactions. Seventeen studies were located. Studies were classified according to the paradigm used to examine reactivity, the setting in which the study was conducted, the identification of the child as a behavior problem, and the occurrence and direction (i.e., increases or decreases in the observed behavior) of reactivity. The results indicated that the awareness paradigm has been employed most frequently, the laboratory has been the primary setting utilized, and problem and nonproblem children have been employed with approximately equal frequency. Reactivity was reported in about three-fourths of the studies. For adults positive and neutral verbal and physical behaviors were more reactive than negative behaviors. The positive and neutral behaviors typically increased in the observer's presence. For children conclusions are not warranted at this time as too few studies have examined children's behavior.Preparation of this article was supported in part by NIMH Grant MH28859-01.     

Model selection and Akaike's Information Criterion (AIC): The general theory and its analytical extensions

During the last fifteen years, Akaike's entropy-based Information Criterion (AIC) has had a fundamental impact in statistical model evaluation problems. This paper studies the general theory of the AIC procedure and provides its analytical extensions in two ways without violating Akaike's main principles. These extensions make AIC asymptotically consistent and penalize overparameterization more stringently to pick only the simplest of the “true” models. These selection criteria are called CAIC and CAICF. Asymptotic properties of AIC and its extensions are investigated, and empirical performances of these criteria are studied in choosing the correct degree of a polynomial model in two different Monte Carlo experiments under different conditions.     

Ethical attentiveness

Kantian virtue can be construed as a condition of an agent which secures adherence to the requirements of morality in the face of the ever-present possibility of inner conflict with counter-ethical considerations. This paper claims that this conception of virtue does not fit in well with one essential characteristic of the virtuous agent; that he or she is attentive to the well-being of others. After some preliminary remarks about virtue-related evaluations, the paper criticises the Kantian conception of virtue in the light of certain characteristics of ethical attentiveness. The paper concludes by developing a notion of ethical habituation which includes the training of attention.

Thwarting the renewal (relapse) of conditioned fear with the explicitly unpaired procedure: Possible interpretations and implications for treating human fears and phobias

In three experiments using the barpress conditioned suppression task with albino rats, we studied the renewal (relapse) of conditioned fear in an ABA fear-renewal paradigm. We found that explicitly unpaired (EU) deliveries of conditioned stimuli (CSs) and unconditioned stimuli (USs) in Context B thwarted fear renewal in Context A. Evidence contraindicated a suggestion by Rauhut, Thomas, and Ayres (2001) that US habituation plays a key role in this effect. For example, renewal was thwarted only when EU CSs and USs were intermingled rather than given in succession. The possibility that EU treatments thwart renewal by creating a CS that inhibits fear in the test context also received no support. Thus, summation and retardation tests in Context A found no evidence that the EU CS became inhibitory, finding instead evidence for a residual excitation. Other possible interpretations of the results and some implications for clinical practice are noted.     

国外婴儿动词习得的两种研究范式

通过介绍国外婴儿动词习得的研究范式, 一是习惯化研究(Habituation paradigm), 二是多通道优先注视范式(IPLP), 来揭示婴儿语言前概念形成的认知心理。国外的研究表明, 婴儿的动词习得晚于名词学习; 动词的成分习得(路径成分或是方式成分)在婴儿周岁前也有时间先后; 动词完整意义的获得还与母语的输入有密切关系。综述说明, 采用这两种研究范式研究语前婴儿的语言认知是较为经济和有效的。     

Criterion knowledge: A moderator of using the recognition heuristic?

The recognition heuristic (RH) claims that people base inferences on recognition only. This has been questioned by several studies which found that additional knowledge was influential. However, in some of these studies, participants' additional knowledge might have encompassed criterion knowledge thus rendering any inferential strategy superfluous. The present study was therefore designed to test the effect of criterion knowledge on use or non‐use of the RH. Eighty‐one participants made pair‐wise comparisons with respect to the size of Belgian cities and also provided estimates of the cities' actual size. We found that relative criterion knowledge (i.e., knowledge about the relative position of an object on the criterion dimension) did indeed play some role, but its exclusion left the main critical findings intact, nonetheless. We thus conclude that previous studies conducted in the paradigm of natural recognition should not be generally refuted by the argument of participants possessing criterion knowledge.
